Haematological and plasma biochemical parameters in endurance horses during training.

This research studied eleven horses undergoing a 12-week training schedule, observing their haematological values and plasma biochemical profile, and found that routine screening of these parameters provided little to no useful information in evaluating a horse’s fitness under these conditions.

Overview of the Study

• In this research, the health and fitness of endurance horses were examined during a 12-week training schedule, specifically focusing on the horses’ haematological (blood) values and plasma biochemical parameters.
• The challenge was to determine whether changes in these parameters could be used in a practical sense to gauge the physical condition and well-being of the horses over the course of the training period.

Haematological and Plasma Biochemical Parameters

• Each horse was subject to regular blood samples. These were analyzed for haematological values, which included measures like red blood cell count, white blood cell count, and platelet count.
• Beyond the blood counts, a wide-ranging biochemical profile was studied from the horses’ plasma. This covered parameters like sodium, potassium, chloride, bicarbonate, glucose, creatinine, urea, bilirubin, iron, total protein, albumin, alkaline phosphatase, aspartate aminotransferase, creatine kinase, gamma glutamyl transferase, calcium phosphate, and cholesterol – all substances that could potentially provide insight on the physical health and functional efficiency of the horse’s vital organs like kidneys, liver, and muscles.

Main Findings from the Study

• Despite the comprehensive nature of the study in looking at myriad blood and biochemical parameters, only a few significant changes were detected in these horses’ measurements as they went through the training schedule.
• The researchers concluded that routine haematological and biochemical screening might not be useful for assessing the fitness of horses under such conditions. This could be due to the fact that the selected parameters do not fluctuate dramatically enough in a trained and healthy horse under normal exercise conditions to be a reliable measure of their physical readiness or health.

Implications of the Study

• The findings bring into question the value of routine blood and biochemical assessments for understanding the physical health and fitness level of horses undergoing endurance training.
• The results could prompt further research into alternative strategies that might provide more valuable and tangible measures of an endurance horse’s fitness status.
